Dream about a hotel burning in the 1950s - - good dream interpretation...

[Don Quijote de la Mancha]

...help needed, please? In my dream, I was looking into the past, in the late 1950s. I saw a six story hotel. Outside of the hotel, there was a large swimming pool, and there were young women from the 1950s in their 1950s bathing suits, which of whom had their children with them. Some people were standing near the area surrounding the pool, while some of the women and children were playing in the water.

Then, a voice cried, "Everyone, please leave - - the hotel is on fire! Some of the people who were outside began leaving the inn, while some people who were in the pool outside did not listen to the warning about the fire. Instead they acted as if they didn't ever hear a single word about the warning that was being said. These people who ignored the warnings kept swimming in the pool, mostly mother's and their kids, as the smoke from the hotel began to infiltrate the swimming pool area; and they acted like nothing was happening.

So, what does this dream mean?
